How it works

OneSlot runs a short, public auction for a single sponsorship slot. No rate card guessing, no back-and-forth email negotiation.

1. You list one slot

One real, upcoming placement: a newsletter main sponsor, an integrated YouTube segment, a podcast episode read, or a website/community placement. You set the exact deliverables, the delivery date, the starting bid and the currency.

2. You invite brands

You invite sponsors you already have a relationship with, up to 15 per auction. Brands can also request access from the public auction page. Every bidder must use a work email on their own company domain — free email providers are rejected — and you approve or decline each one before they can bid.

3. Verified brands compete

The auction runs for 24 or 48 hours. Bids are validated on the server, appended immutably, and shown publicly with the company name. A bid placed in the final two minutes extends the clock, so nobody wins by sniping.

4. The winner confirms

When the clock stops, the highest valid bid becomes the provisional winner and gets a short confirmation window. If they decline or run out of time, the slot is offered to the next highest bidder automatically. Payment and delivery are arranged directly between you and the sponsor, and both sides confirm the handoff on OneSlot.

What OneSlot does not do

  • It does not hold funds or process payments.
  • It does not sell audience data.
  • It does not let anonymous or unverified accounts bid.
